Bulletproof helmets are made from
1 lexan
2 saran
3 glyptal
4 thiokol
Explanation:
Bulletproof helmets are made up of lexan. it is a polycarbonate polymer nearly as tough as steel. It is used in bulletproof windows and as face plates in the helmets worn by astronauts. Lexan is made by condensing phosgene with a diphenol with the elimination of \({\rm{HCl}}{\rm{.}}\)

Which among the following polymers is used for making handles of cooker?
1 Bakelite
2 Novolac
3 Melamine
4 Acrilan
Explanation:
Bakelite is used for making handles of cooker. On heating with formaldehyde, novolac undergoes cross-linking to form an infusible solid mass, which is called bakelite. It is a thermosetting palstic. It is a bad conductor of heat. It does not allow heat to pass through it easily. So, it is used to make the handles of the utensils, so that it does not heated and it becomes easy to handle the cookware while cooking.
